drm/amd/display: Fix to be able to stop crc calculation
[Why] Find out when we try to disable CRC calculation, crc generation is still enabled. Main reason is that dc_stream_configure_crc() will never get called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE. [How] Add checking condition that when source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE, we should also call dc_stream_configure_crc() to disable crc calculation.
